21 Claims.

- This invention relates to printing machines andmore particularly tostructural sections adapted for use therein.

In printing machines of the character through which printing or likedevices are sequentially fed, it is customary to feed the devicesthrough the machine in a step-by-step manner and in the course of suchmovement the devices come to rest in printing position in the machinewhereat impressions are made therefrom. While a wide variety of printingdevices, of the character sequentially fed through printing machinessuch as those to which the present invention pertains,

have heretofore been provided, that disclosed in Mohler Patent No.1,812,894, patented July 7, 1931, is typical of such devices. A printingdevice of this kind includes a carrier or frame having an embossablemetal plate removably retained in position thereon, type charactersbeing embossed on such a plate to appear in relief on the operative facethereof. Type characters have also been embossed in a so-calledone-piece printing device of the character disclosed for example inDuncan Patent No. 1,026,246, patented May 14, 1912, and devices of thischaracter are frequently utilized in printing machines of the kind towhich this invention relates. Furthermore, in some instances typecharacters have been formed in suitable stencil paper, carried by aframe of cardboard or other material, and suitable means have beenprovided in printing machines through which such devices were fed toapply ink to the. type characters on printing devices of this characterand for pressing a sheet into engagement with the inked type charactersto thereby have an impression made thereon. Irrespective of whetherprinting devices embodying embossed type characters, or type charactersafforded in a stencil sheet, were utilized, it has been necessary, inprinting machines through which the devices were passed, to applyappreciable pressure in order that clear cut and otherwise satisfactoryimpressions would be produced in the machine.

In the printing machines through which printing or like devices of theaforesaid character, for example, are sequentially fed, the printingdevices, in the course of the step-by-step movement thereof through themachine, come to rest at printing position in the machine on an anvilbeneath an ink ribbon and a platen or other suitable means is operatedto force a sheet overlying the ink ribbon toward type characters on thedevice whereupon an impression is made on the sheet from the typecharacters. Heretofore flat ing machines of the aforesaid character.

and roller platens have been employed in' print- A flat platen of thischaracter has customarily included a head embodying a flat face ofresilient material, the head having been carried by an arm which wasreciprocatedto move the flat resilient face on the head to and from theoperative position whereat impressions were made from the printingdevice at printing position in the machine in the aforesaid manner. Atypical roller platen such as hasbeen heretofore employed has included aresilient periphery and has been so mounted in the machine that itwasmovable to and from operative cooperation with a printing device onthe anvil and customarily such a platen has been rolled across the typecharacters on the printing device on the anvil to effect a printingoperation.

Heretofore it has been custom yv to mount the anvil, or other means onwhich the printing devices come to rest during the time impressions aremade therefrom, on the frame of the machine and to also mount theplaten, or other means operative to press the sheets into engagementwith the type characters on the printing device resting on such ananvil, on the frame of the machine. In such an arrangement the stressesattendant to the application of pressure to effect the printingoperation have been transmitted through the frame of the machine. Thishas necessitated that such frames be of rigid construction so as to becapable of dissipating the stresses attendant to the printing operationswithout undue deflection occurring in the various operative parts. Thishas also required that the operative parts themselves be constructed soas to effectively resist material deflection. It will be appreciatedthat deflection in the frame of printing machines or in the partsoperative to effect printing operations in such machines might result insmudging the impressions, or in the production of uneven impressions,which is to say, the making of some parts of an impression heavier thanother parts, and material deflection is objectionable for other reasons.

In those instances where embossed type characters have been provided onprinting devices of the character that are sequentially passed throughprinting machines of the kind to which this invention pertains, the typecharacters are customarily arranged in rows that extend across thedevices transversely to the'line of movement thereof through themachines. Moreover, where roller platens have been employed for makingimpressions from type characters arranged in this manner, the axes ofthe roller platens have extended in substantially parallel relation withthe extent of the rows of type characters. Frequently the rows of typecharacters afford an arrangement from which a name, street and number,city and state or the like constituting an address may be printed and itwill be appreciated that in such an arrangement the length of variousrows of type characters will vary. For example, the name may berelatively short, the street and number may be relatively long, and thecity and state may be of a length intermediate the length of the nameand thelength of the street and number and, of course, other widevariations in the lengths of the lines may occur. Thus, particularlywhere a roller platen is employed for making impressions of the typecharacters so arranged and the roller is caused to move across thedevices so as to advance from one line to another, there may be atendency for the roller platen to make heavy impressions from shortlines and lighter impressions from long lines of 'vices of the charactersequentially fed through printing machines, be so arranged that materialdeflection in the parts in the course of impres-- sion operations in themachine will be avoided and an important object of this invention is toso arrange the parts operative to make impressions from printing devicesin printing machines that objectionable deflection therein in the courseof impression operations will be prevented.

Sufiicient rigidity soas to avoid objectionable deflection may ofcoursiejbe imparted by forming the parts to include sufficient materialto resist objectionable deflection but where castings, forgings ,orconventional structural sections have been employed for this purpose, ithas been necessary to make the parts quite heavy and this has beenobjectionable because it is advantageous to have printing machines ofthe aforesaid charactar as light in weight as is consistent with emcientoperation and the use of relatively heavy sections is objectionable froma cost standpoint and for other and kindred reasons.

Thus, still another important object of this invention is to so arrangethe parts entailed in the performance of impression operations inprinting machines that objectionable deflection in such parts in thecourse of impression operations effected thereby will be prevented butat the same time to construct such parts so as to be as light as will bepossible consistent with emcient and proper operation.

It has been mentioned hereinabove that it isobjectionable to transmitthe forces attendant to impression operations in printing machines ofthe aforesaid character through the frames of such machines and in viewof this it is another object of this invention to so arrange the partsentailed in the performance of impression operations in printingmachines that the stresses attendant to the performance of suchoperations will not be transmitted through the frame of the machine inwhich the impression operations are effected and an object ancillary tothe foregoing is to arrange the support on which the printing devicesrest during impression operations, and the means for applying theimpression producing pressure, in a unitary member in which all theforces attendant to the performance of impression operations will beabsorbed and dissipated.

More specifically it is an object of this invention to support an anvilon which the printing devices may rest while impression operations areperformed thereon in a unitary structure, also affording a support forthe platen or other member employed for applying the impressionpressure.

While it is essential that such deflection as might impair theproduction of clear cut and otherwise satisfactory impressions in theparts entailed in the performance of impression operations in printingmachines be avoided, it is at the same time desirable that somedeflection be afforded so as to compensate for variations in thethicknesses of sheets or the like on which the impressions are made andthus yet another important object of this invention is to prevent suchdeflection in the parts entailed in the performance of impressionoperations in printing machines as may impair the production ofsatisfactory impressions and yet at the same time afford as muchdeflection as may be required to afford such compensation, forvariations that may be encountered, as may be needed.

In order that the foregoing and other and kindred objects of thisinvention may be realized, I utilize sheet metal plates and I so form,arrange and join these plates that supports for both an anvil or thelike and a platen or other pressure member are afforded in the unitarystructure made from such plates.

' for the parts entailed in the performance of such operations and anobject related to the foregoing is to weld together metal plates formedand arranged in a selected manner so as to thereby afford a novelunitary structural section.

While the present invention is particularly useful in printing and likemachines, it is to be understood that the structural section to whichthis invention primarily pertains will be useful in other machines suchas, for example, punching machines and presses and in other instanceswhere it is necessary to dissipate stresses attendant to the productionof opposing forces and thus while the present invention is describedwith particular relation to printing machines of the character throughwhich printing devices are sequentially fed, it is to be understood thatwhile this is the preferred it is not the sole embodiment of the presentinvention and that therefore the invention is not to be considered asbeing limited to use in printing machines of the aforesaid character.

Other and further objects are to so form metal plates that, when suchplates are joined into a unitary structure, maximum resistance todeflection will be afforded; to so form plates, as aforesaid, thatinterconnection along abutting edges thereof may be effected by weldingthe plates together to afford a unitary structure: to so incorporate ananvil or the like and a platen arrangement or the like in a unitarystructure that what may be called a printing frame will be afforded; toso form and relate the metal plates of such a printing frame thatbearing means for operating shafts for operative parts on theline 3-3 onFig. 1;

lines 2545, 26-46, 21-21 and2828 on may be extended therethrough withoutreducing the structural rigidity of the frame; and to so form and relatethe metal plates of such a structure that the assembly and weldingoperations may be readily and easily performed and efficiently inspectedupon completion of the frame.

Other and further objects of the present invention will be apparent fromthe following description and claims and are illustrated in theaccompanying drawings which, by way of illustration, show a preferredembodiment and the principle thereof and what I now consider to be thebest mode in which I have contemplated applying that principle. Otherembodiments of the invention embodying the same or equivalent prin- Iciple may be used and structural changes may be made as desired by thoseskilled in the art without departing from the present invention and thepurview of the appended claims.

The machine illustrated in the accompanying drawings in which the novelprinting frame of this invention is utilized is described in detail inmy co-pending application, Serial No. 388,998, filed April 17, 1941, andreference may be made to this application for a detailed description ofthe various, operative parts .of the machine. Briefly, however, thismachine includes a table top T on which sheets such as envelopes.letterheads, bill forms, ledger sheets and the like may be arranged toreceive impressions from printing devices or the .like sequentially fedthrough the machine, the devices being introduced into the magazine Mand being successively withdrawn from the bottom of the stack thereof inthe magazine by the arrangement described in detail in my co-pendingapplication, the printing devices being advanced through the machine ina step-by-step manner and in the course of such movement coming to restin operative relation with the platen P to have one or more impressionsmade therefrom upon operation of the platen. At the time the printingdevices come to rest in operative relation with the platen P,

they are disposed. on an anvil A which, along with the platen P, iscarried by the novel printing frame of this invention.-

The platen P is preferably a so-called roller platen and while thisplaten may be operated in a wide variety of ways, an advantageous way ofso operating this platen is described in full detail in my co-pendingapplication, Serial No. 361,530 filed October 17, 1940. In the presentinstance, however, the platen P is carried by a carriage C havingsupporting and guid ng rollers thereon which travel on tracks 52provided en the carriage support plate 53 adiustably connected to theplaten head forging 54, described more fully hereinafter. The carriageplate 53 is connected to the head 54 for vertical adjustment movementwhich is effected by an adiusting knob 55, and by rotation of the knob55 it is possible to vary the pressure exerted by the platen P in thecourse of rotation thereof. The

- particular manner in which this adjustable interconnecticn is afiordedis described in full detail in myaforesaid co-pending application, Ser.No. 361,530, this adjustability also enabling the platen P to beadjusted relative to the printing devices which come to rest on theanvil A so as to insure that the platen will uniformly cooper- 5 atewith type characters afforded on the printing devices so as to produceuniform impressions.

In the course of operation of the machine, the shaft 60 is set inoperation and through the intermediary of an eccentric 6| thereon isoperative through the adjustable link 62 to rock the arm 63 fast on ashaft 64 mounted in a manner described in further detail hereinafter.The shaft 64 also has an arm '65 thereon at the end there of oppositethat at which the arm 63 is mounted, 15 and a link 66 is pivotallyconnected to the free end of the arm 65, the opposite end of this linkbeing pivotally connected to the free end of an arm 61 fast on a shaft68 mounted in a manner described in further detail hereinafter. At theend of the shaft 68 opposite that at which the arm 61 is fast, there isan arm 69. The arm 69 has a transverse pin fixed therein at its free endthroughwhich an operative connection is provided to the platen carriageC. Hence, 'in the course of operation of the shaft 60, a reciprocatorymovement along the platen support 53 is imparted to the carriage C. Inthe course of this 7 reciprocatory movement means described in detail inmy aforesaid co-pending application, Ser. No. 361,530 are effectivethrough the toggle 1I to lower the platen P into operative relationwiththe printing device resting on the anvil A, and in the course ofreciprocation of the carriage C, after the platen P has been loweredinto operative relation with a printing device, an impression is madefrom the type characters on the printing device onto a sheet disposedbeneath the platen P, an ink ribbon (not shown) being interposed betweentype characters on the printing device and said sheet.

The printing frame I00, which is the novel structural section to whichthis invention primarily pertains and one which the anvil A and theplaten P are mounted, is mounted on the main supporting frame IOI of theprinting machine, which main frame also carries the table top T. Asshown in Fig. 1, the printing frame I is associated with the rectangulartable top T so as to extend diagonally with respectthereby. The frame INis formed to provide a pair of supporting rails I02 and I03 that extendparallel to the front edge of the table top T, these supporting railsbeing employed in mounting certain of the operative parts of theprinting ma- 55 chine and also serving as the support for theprintingframe I00.

The printing frame I00 is of a generally 0- shaped' configuration andincludes an upper arm or section I05 and a lower arm or section I06which project in a generally parallel relation from a vertical portionI01 therein. The vertical portion I01 of the printing frame extendsthrough the table top T adjacent the right rear corner thereof, as shownin Fig. 1, so that the upper arm I05 extends diagonally across the ta-'ble top T in upwardly spaced relation with respect to the table top,while the lower arm I06 extends beneath the table top T and in thecomplete machine is concealed and housed within the frame I0l.

In the course of operation ofthe machine, the force required to effectthe desired printing operation is applied between the anvil A and thehead forging 54 through the extension of the.75

toggle mechanism II of the platen, and this force is so applied that thetendency is to separate the opposed arms I05 and I06 of the printingframe I00. The printing frame I00 is therefore constructed to resistsuch separating effect of the force which is thus applied between itsarms I05 and I06, but at the same time, I have so formed the printingframe that it has a pleasing appearance suitable for incorporation in aprinting machine of the character herein and also as to avoid thenecessity for further housing or concealing of unsightly parts.

In attaining the foregoing, the printing frame I00 is constructed from aplurality of independently formed parts most of which are made fromsheet metal or sheet steel stock, these independently formed parts beingthereafter assembled and then securd in the desired rigid relationshipby welding. The desired rigidity is also in some instances assured bymechanical interlocking of these separately formed elements.

The several separately formed elements which enter into the productionof the printing frame I 00 are shown in an exploded relationship in Fig.10 of the drawings, the parts being shown in this view in such a way asto indicate the relationship therebetween in the completed printingframe I00. Thus, as shown in Fig. 10, a central plate H0 is provided,which is generally 0- shaped in form so as to provide an upper arm H5and a lower arm II6 connected by an integral intermediate verticalportion I I1. This central plate H0 is adapted to be enclosed within orbetween two shell-like members I20 and I30 which are adapted to beplaced on opposite sides of the central plate III! with the edges of theshell-like members I20 and I30 substantially registered with thebordering edges of the central plate II0.

The shell-like member I20, which will hereinafter be termed theleft-hand shell member, has an upper arm I25, 2. lower arm I26 and anintermediate vertically extending connecting portion I21. The arms I25and I26 and the vertical portion I21 of the shell-like member I20 aregenerally channel-like in cross section, as

will be seen from a comparison of Figs. 5, 10 and l 31', thischannel-like form being such that the width of the channel, that is, thewidth of the web thereof, varies in the extent of the arm I25 so as tobe considerably wider at the rear end of the arm I25. Similarly the webof this chan- 4 nel is relatively wide as it extends through the lengthof the vertical portion I21 of the shelllike member I20 and the widththereof gradually decreases" from the rear end of the arm I26 toward theforward end thereof. Thus, the channel-like form of the arm I25 isprovided by a web portion I25W having upper and lower flanges I25 andI25" extending from the upper and lower edges of the web I25W. As shownin Figs.

5 and 31, the flanges I25 and I25" diverge slightly so that the openface defined by the edges of the flanges I25 and I25" is at all pointsalong the arm I25 slightly greater in width or vertical dimension thanis the web I25 at the corresponding point along the arm.

At the rear end of the arm I25, the web I25W merges with an integral webI21W of the vertical portion I21, and the rear portion of the upperflange I25 merges with a flange I21 which forms the rear flange of thevertically extending portion I21. The two flanges I25'-and I21 arepreferably merged through a curved rear corner,

as indicated at I40.
